Rexroth & Hydac Series High-Performance Industrial Filter Elements

Product Overview:

This series of filter elements is engineered to meet Bosch Rexroth part standards and Hydac 2700R high-flow return specifications, providing premier fluid cleanliness for heavy-duty hydraulic systems. Utilizing advanced PWR20 (Betamicron) glass fiber technology, these elements achieve exceptional particle retention even under high differential pressure. In 2026, these filters are essential for steel mills, mining equipment, and large power units, maintaining fluid integrity to ISO 4406 standards while offering low pressure drop and high dirt-holding capacity.

Featured models: R939059247, 2700R025W/HC, 311275-1.1401, PWR20-A00-0-M, and R928045177.

Key Technical Advantages:

• PWR20 Patented Media: Features multi-layer composite microfiber with an outstanding $\beta_x(c) \ge 1000$ efficiency. The PWR20 grade is optimized for 20-micron particle capture, balancing precision with high flow throughput.

• High-Flow Return Optimization (2700R): Reinforced specifically for 2700R sizes, these elements withstand instantaneous return surges up to $2700 \text{ L/min}$, preventing media fatigue under high-frequency vibration.

• W/HC Reinforced Mesh: The 025W/HC variant combines stainless steel reinforcement with glass fiber, offering superior structural integrity for high-viscosity fluids or challenging cold-start environments.

• High-Collapse Internal Core: Utilizing thickened galvanized steel cores, the collapse resistance meets rigorous industrial standards, protecting downstream components even if the element is severely clogged.

• A00-0-M Precision Interface: Manufactured strictly to PWR20-A00-0-M standards, ensuring $100\%$ physical interchangeability with original housings and zero bypass leakage.
